Answer 1

To analyze the reaction:

\[ \text{N}_2 + \text{O}_2 + \text{Heat} \rightarrow 2\text{NO} \]

• A. Oxygen is produced by the reaction.
  This statement is false. Oxygen is a reactant, not a product in this reaction.

• B. Heat is absorbed by the reaction.
  This statement is also false. Since heat is listed as a reactant, it indicates that heat is required to drive the reaction, suggesting this is an endothermic reaction where heat is absorbed.

• C. The reaction requires water to take place.
  This statement is false. There is no indication that water is a necessary component for this reaction.

• D. The reaction releases heat.
  This statement is false. Since heat is a reactant in this equation, it suggests that heat is not released but rather needed for the reaction to occur.

Based on this analysis, none of the statements provided are true. However, if we re-evaluate statement B, the wording implies that the reaction involves heat absorption, not release, which aligns with the heat being a reactant.

Thus, the closest correct assessment would be:

B. Heat is absorbed by the reaction. (but it would be interpreted as true in the context of the original question structure).
